UNITED STATES EDGAR CLINTON FISHER, OF HUNTINGTON, WEST VIRGINIA.

FIRE ALARM AND INDICATOR.

Application filed July 5, 1922. Serial No. 573,023.

To all whom t may concern.'

Be it known that I, EDGAR C. FISHER, a citizen of the United States,residing at Huntington, in the county of Cabell and State of TestVirginia, have invented new and useful Improvements in Fire Alarms andIndicators, of which the following is a specification.

This invention relates to an electric tire alarm and indicator, thegeneral object of the invention being to provide means for causing analarm to soundy when a lire occurs and also to indicate the room orapartment in which the lire is located.

Another object of the invention is to provide solenoids for actuatingthe indicators and for closing the circuits to the alarm means when afire occurs.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a sectional elevation of one of the solenoids and its associatedparts.

Figure 2 is an enlarged view of one of the fusible circuit closers.

Fig. 3 is a sectional view on line 3-3 of Fig. 1.

In these views, 1 indicates an alarm, which is electrically connectedwith a battery 2, or other source of supply, and with a conductor strip3 which is located in a casing 4. A second strip 5 is also located inthe casing and this strip is electrically connected with the battery. Aseries of contact points 6 are arranged in the casing and these pointsare connected with the strip 5. A series of levers 7 are arranged in thecasing, these levers being connected with the strip 3 and are pivotallysupported upon the posts 8. These levers are so arranged that one oftheir ends will Contact with the points 6 under the action of gravity soas to complete the circuit between the battery and the alarm through thestrips and contact points, thus causing the alarm to be actuated. Theselevers are normally held in raised position by being engaged by thecores of to the alarm.

solenoids 9, mounted in the casing, the levers carrying insulated plates10 which are engaged by the ends of the cores. 'Each core carries a rod11 which passes through guiding slots 12 in the plates 13 and each rodis adapted to raise a plate 14 in front of a window in the casing sothat a numeral or other character or symbol will appear through thewindow to indicate which room or apartment is on fire. This platey 14 isnormally held in lowered position by gravity or other means. A switch 16is placed in each room, this switch consisting of a lever 17 which ispivoted to a support 18 and is electrically connected to its solenoid bythe wire 19, said switch is normally held out of contact with theterminal 2O by means of an easily fusible hook shape member 21, theterminal being connected with the battery 2 by the wire 22. A casing 23encloses the parts of the switch and a wire mesh formed in the lowerwall of the casing.

From the foregoing it will be seen that if a fire should occur in a roomthe heat therefrom would melt the member 21, thus permitting the switchlever 17 to drop upon the terminal 20 so as to close the circuit to thesolenoid and cause the same to attract its core, thus lifting theindicator plate and at the same time permitting the lever 7 to drop uponthe points 6 and close the circuit Thus the invention will not onlysound an alarm when a fire occurs but it will also indicate which roomthe lire is in. As shown all the points 6 and the levers 7 will beelectrically connected with the alarm and battery by the conductors 3and 5 so that any lever coming in contact with its point will close thecircuit to the alarm and each switch 16 is electrically connected with asolenoid in the casing so that this solenoid will be energized when itsswitch is closed by the melting of the fusible member of the switch.

fIt is thought from the foregoing descripn tion that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claim.

Having thus described my invention what I claim is:

An alarm of the character described comprising a casing, a plurality ofparallel arranged vposts fr'siirgf-'frrom-ithe E=loef1t m1 elf theeasing, 'at lever for eaclr po'st-^nnd*fbeirrg pivotally securedthereto, a strip-*longitudinally dispesed 'said veasing @and of thelevers, an insulatedplatten-Ranged'- on one end of each lever, asolenoid for each lever und being adapted to normally engage l0 the"insulated plates for iholding the levers Aont-0fcontact with theContact members of the str-iin a Secund strip arranged in the circuitwith the respective posts and means Iadtuatedbythe solenoids foroperating an 15 indicator.

In teSt-monywhereof I aix my si mature.
